11'; (ii/Z 1071 0772 it ntzry concern:

Be it known that I, GEORGE O. STURTE- VANT, a citizen of the United States, residing at Athol, in the county of Worcester and State of Massachusetts, have made certain new and useful Improvements in Steam- Boilers, of which the following is a specification.

My invention is an improvement in steamboilers; and it consists in certain novel constructions and combinations of parts hereinafter described and claimed.

Referring to the drawings forming a part hereof, Figure 1 is a perspective view of my boiler, and Fig. 2 is a longitudinal section thereof.

In the practical application of my invention I provide a boiler A of ordinary construction and for supporting the same a lining B instead of the usual brickwork, the brickwork being carried up only as far as the gratebars. The lining B is composed of plates 1) l), spaced apart and secured together by' stay-bolts b and comprises side walls I) 5, each provided with a plurality of upward extensions 5 I) 11 5 respectively, a centrally-arranged cross-wall b, and an end wall 7) having openings 6 therethrough for the ingress of fuel. It will be understood that the opening between the plates is continuous in all of the walls.

At the rear of the boiler I arrange the arched lining I)", constructed in a similar manner to the supporting-lining. The boiler is supportedon the cross-wall and end wall and by angle-plates 6 resting on suitable seats 6 between the extensions and at the front and rear end of the side wall.

WVater-feed pipes C C connect the supporting-lining and the arched lining, respectively, with a source of water-supply, and the waterfeed pipe C connects the front of the boiler with the supporting-lining.

Steam-pipes D D extend between the oppositely-disposed upward extensions across the boiler and are connected by T-joints d d with pipes leading from the boiler, while a steam-pipe D extends from the arched lining and is connected with the cross-pipe D by a T-joint (1 A water-circulation pipe E connects. the arched lining with one of the side walls at the lower parts thereof, and a water-column F extends from the front end of the left side wall upwardly and inwardly to the forward extension of that side.

With my construction of boiler and sup port I am able to secure a maximum of heat, since all the radiation from the furnace-wall is utilized in heating the water. The radiation from the boiler is also utilized to a considerable extent.

The lining is provided with a five-inch water-space and may be made to fit any boiler, and for convenience in cleaning the same I provide the hand-holes covered by the plates G G and the blow-off e on the pipe E.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of a steam-boiler, a supporting-lining therefor composed of plates spaced apart and secured together by staybolts, and comprising side walls, provided with a plurality of oppositely-arranged upward extensions, a centrally-arranged crosswall, and an end wall provided with a plurality of openings therethrough for the in gress of fuel, a similarly-constructed arched lining at the rear of the boiler, water-feed pipes connecting the supporting-lining and the arched lining with a source of water-supply, a water-circulation pipe connecting the arched lining with the supporting-lining, a water-feed pipeconnecting the front of the boiler with the supporting-lining, steampipes connecting the opposite extensions with each other, and with the boiler, a steampipe connecting the arched lining with the boiler, and a water-column connecting the end of a side wall and its extension.

2. The combination of a steam-boiler, a supporting-lining therefor composed of plates spaced apart and secured together by staybolts, and comprising side walls provided with a plurality of oppositely-arranged upward extensions, a centrally-arranged crosswall and an end wall provided with a plurality of openings therethrough for the ingress of fuel, a similarly-constructed arched lining at the rear of the boiler, means for supplying water to the arched lining and the supporting-lining, means permitting the circulation of water between the arched lining and the supporting-lining, means permitting the circulation of water between the boiler and the supportinglining, meansfor permitting the passage of steam from the supportinglining and the arched lining to the boiler, and a water-column connected with the front end of a side wall.

3. The combination of a steam-boiler, a

supporting-lining therefor, composed of plates.

spaced apart and secured together by staybolts, and comprising side walls provided with a plurality of oppositely-arranged upward extensions, a centrally-arranged crosswall, and an end wall, a similarly-constructed arched lining at the rear of the boiler, waterfeed pipes connecting the supporting-lining and the arched lining with a source of watersupply, and with each other, and with the boiler, steam-pipes connecting the supporting-lining and the arched lining with the boiler, and a water-column on the support- 1ng-lm1ng.

4. The combination of a steam-boiler, a supporting-lining therefor, composed of plates spaced apart and secured together, and comprising side walls, a cross-wall and an end wall, a similarly-constructed arched lining at the rear of the boiler, water connections between a source of water-supply, the arched lining and the supporting-lining, and between the supporting-lining and the boiler,

steam connections between the arched lining and the supporting-lining, and the boiler, and a water-column on the supporting-lining.

5. The combination of a boiler, a hollow front support therefor, hollow side supports therefor communicating with the front sup port, a hollow arch at the rear of the boiler, water connections between a source of supply, the side supports, the hollow arch, and the boiler, steam connections between the side supports, the hollow arch and the boiler, and a water-column on the front of the side support.

6. The combination of a boiler, a hollow front support therefor, hollow side supports therefor, and communicating with the front support, water connections between a source of supply, the side supports and the boiler, steam connections between the side supports and the boiler, and a water-column on one of the hollow side supports.
